Demolishing and rebuilding an existing house is a great way to create a self-build project, especially in the countryside where good plots are scarce. But the economics of demolition and rebuild can be unattractive, unless you can build a much larger house than the one you’re demolishing. But with planning policies often placing tight restrictions on the size of replacements, what can be done to maximise on the opportunities that are out there?
Whether you’re building in an urban area or out in the countryside, planning policies should generally allow you to replace one house with another. You can sweep up both planning permission to demolish (which is needed for houses) and permission for the new house in one application. Don’t think about demolishing first, then applying to rebuild because (especially in the countryside) the existing house is the only reason you can build a new one. Lose this and you could lose the right to rebuild.
